Is Caffeine Wrecking Your Exercise Performance?

Coffee is known for its energy-increasing caffeine, not to mention delightful flavors and aroma. While millions of people around the world rely on their daily java to boost their energy levels, new research found that it might not be such a great idea when it comes to your exercise performance.

According to the new study published in the International Journal of Sports Nutrition and Exercise Metabolism, coffee may reduce exercise performance. Most people simply assume that if the caffeine in coffee boosts energy than having more energy must also improve exercise, but the study suggests otherwise. The male study participants underwent repeated sprint performance activities. They conducted the tests without any caffeine to establish a baseline and then were divided into groups to receive either caffeinated chewing gum or a placebo, which consisted of non-caffeinated chewing gum.

The researchers found that a low amount of caffeine (40 milligrams daily) on a regular basis was fine for performance, but higher amounts, which were established as greater than 130 milligrams daily, resulted in a worsening of sports performance in the study participants. The study also found that those who consumed about the amount of 2 to 3 cups of coffee daily had a decline in their sprint performance.

Based on the study results, one twelve-ounce cup of coffee daily or two cups of black or green tea is unlikely to affect your sports performance, but drinking more than that may be detrimental to your results.

Red Bull 8 ounces—80 milligrams caffeine

Caffeine increases energy by stimulating the central nervous system, which reduces fatigue and drowsiness. While athletes may turn to these beverages to improve their performance, the study results suggest that 2 or more cups of coffee may have the reverse effect.
